Your vehicle's oxygen sensor works with your engine control unit to optimize your engine's performance. The oxygen sensor is constantly monitoring your vehicle's exhaust and sending input back to the engine control unit so it can modify the vehicle's air fuel ratio based off of it's current conditions.

If the oxygen sensor is not working properly the result could include:

Reduced fuel mileage

Failed emissions testing

A check engine light

Poor Drive-ability

NOTE:

This front oxygen sensor has the OE Connector and is a direct fit replacement unit.

This Bosch oxygen sensor should be replaced every
100,000 miles or sooner for best performance

This is the oxygen sensor located before the catalytic converter there are 2 required per vehicle (upstream)
